SPECIFICATION forming part of Letters Patent No. 400,154, dated March26, 1889.

Application filed November 27, 1888. Serial No. 291,983. (No model.)

To all whom it may concern.-

3e it known that I, OREN WILLIAMS, of

Gouverneur, in the county of St. Lawrence and State of New York, haveinvented a new and Improved Snow-Plow, of which the following is a full,clear, and exact description.

My invention relates to an improvement in snow-plows, and has for itsobject to provide a plow of simple and durable construction which willexpeditiously remove the snow from the track, leaving a solid compactwall at each side; and the further object of the invention is totransport the snow as removed to quite a distance at one side of thetrack.

The invention consists in the novel construction and combination of theseveral parts, as will be h ereina'fter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the device. Fig. 2 is a central verticallongitudinal section. Fig. 3 is a partial plan view; and Fig. l is atransverse vertical section taken on line 5cm of Fig. 2, illustratingthe relative position of the horizontal and vertical conveyers.

In carrying out the invention the body of the snow-plow is constructedsimilarly to a box-car and is mounted upon suitable trucks. The box-body10 is adapted for the reception of an engine, (which is not illustratedin the drawings) the driving-shaft 1O thereofonly being shown.

From each side of the box-body arms 11 are forwardly projected, as bestshown in dotted lines, Fig. 1, and a second or outer frame isconstructed at each side of the body, the same consisting of metal arms12, extending parallel with the mainframe arms 11 from the outerextremity of said arms to a point at or near the center of the box-likeportion of the body. The outer-frame arms 12 are held a distance fromthe main arms 11 by studs or posts 14, intervening, respectively, theforward extremities of the outer and inner arms and the inner extremityof the outer arm and the box-like body.

Between the inner body-arms, 11, a wheel, 15, is journaled, consistingof a drum, 16, mounted upon a suitable axle, 17, the said axle beingjournaled in both the outer and inner arms, 11 and 12, as bestillustrated in Fig. From each end of the drum 16 an annular flange, 18,is upwardly projected, and the said wheel is divided into a series ofpockets, 19, through the medium of transverse semicircular partitions20, extending from end to end of the drum and secured to the flanges inany approved manner. The partitions 20 are made to terminate a slightdistance from the outer edge of the flange, as best illustrated in Fig.2, and the said partitions are so located that their concave faces willbe in direction of the revolution of the wheel.

In front of each. of the partitions 20 a radial slot, 21, is produced,the center of the circle of which slots is immediately above thepartitions, at which point the upper ends of discharge-plates 22 arepivoted, one plate being provided for each pocket. The free ends of theplates 22 are provided with pins 23 integral therewith, which pinsext-end outwardly parallel with the longitudinal face of the platesthrough the severalslots 21, as best illustrated in Figs. 1 and 2.

A trip-plate, 24, is rigidly attached to the inner face of each of theframe-arms 11, which plate is provided with a cam-face, 25, illustratedin dotted lines, Fig. 2, and extends upward above the horizontal planeof the drum portion of the wheel from a forward point, a, to a rearpoint, I), the point a being so located that when the partitions reachthe same they will have assumed virtually a vertical position, and thepoint I) is so placed that the said partitions when reaching the saidpoint will have virtually assumed ahorizontal position, as is shown inFig. 2. The cam-face 25 of the trip-plate is curved, which curve,commencing at u, is gradually swelled to the rear and carried sharplydown to the point 11.

Between the wheel and the box-body 10 an essentially T -shaped tubularcasing, 26, is located, the horizontal member whereof constitutes thebase. The upper member, which intersects the horizontal member, isvertical a portion of its length only, and is then car ried at aninclination outward above the boxlike body and beyond the same.

In the horizontal member of the casing 26 two screw conveyers, 27 and28, are held to revolve, one conveyer being formed with a right-handpitch and the other with a left hand pitch. The inner ends of the twoconveyers are stopped at each side of the center of the horizontalmember of the casing, and between the approaching ends of the twohorizontal conveyersa short vertical conveyer, 29, is journaled in thecasing, which latter conveyer extends upward within the tubular sec tionof the casing. To the upper end of the vertical conveycr 2!) a secondconveyor, 30, is hi nged, the latter conveyor being made to pro ,jectupward within the inclined portion of the the discharge-plates remain inantmtward pocasing to the top thereof, at which point the shaft oi theconveyer journaled in suitable bearings, 33]. llpon the outer end ofeach of the horizontal (-onveyers "27 and 28 a spurgear, 32, is secured,and a pulley, 33, the same being located between the inner and outerarms, ll and l2.

The drive-shaft is provided at each end with a large pulley, 34-, and asmaller pulley, 35, the pulleys 35 being belted. to the pulleys 33,located upon the horizontal eonveyershafts, as best illustrated in Fig 1and 3.

The shat't.1.7of the wheel is provided near each ext: emity,between thearms 11 and 12,wit h a spu rgear, 36,wh i ch spur-gea r meshes with apinion, 37, secured to a spindle, 38, jonrnaled between the arms 11. and12, as best shown in Fig. 3, the said spindle being also made to carry agear, 33$ slightly smaller than the wheel-gear 3b, which gear mesheswith the gear 32, secured to the horizontal convcyershai Thisarrangement of gearing is designed to admit of a rapid motion of thelower conveyors and a cmnparativel y sl ow revolution of the wheels.

The upper vertical. and connected inclined conveyers are adapted to berevolved at least once and a hall or twice as fast as the two lower orhorizontal. conveyers, and to that end upon the lower extremity of thevertical conveyor-shatt a-bevel-gear, 40, .is secured, meshing with asecond bevehgear, -.1-l., secured to one end of a shaft, 42, journaledlongitudinallybeneath the plow, the rear end of which shaft is providedwith a similar bevel-gear, 4-25. 'lhrough the latter bevel-gear aconnection is made with the drive-shaft '10, the same being effected byjournaling a shaft, ll, beneath the box-body 10, which shaft ii isprovid ed with a bevel-gear to mesh with the gear 43, and a pulley, l5,belted to the larger pulley, 3-1, of the drive-shalt it), as illustratedin Fig. 1.

A hopper, 44', is attached to the forward side of the casing 26, whichhopper extends from side to side of the main .t'rame of the plow, andcommunicates with the hm-izontal and vertical portions oi. the saidcasing. The forward end of the hopper is open and faces the wheel.

In operation, as the plow is carried forward through the bank of snow,the dischargeplates of the. 'lorward pockets will be forced brought incontact with the outer edge of the slot 91. The snow is at this pointdischarged into the hopper at}, as illustrated in Fig After dischargingthe snow into the hopper sitionthat is, with their pins in the outerends of the slotsuntil again pressed inward by the snow, as previouslydescribed. Thus the snow is continuously delivered from theseveralpockets of the wheel into the hopper and upon the severalhorizontal conveyors and the lower portion of the vertical conveyor. Thelmrizontal conveyors carry the snow from the sides of the plow anddeliver the same to the vertical conveyor, from wh ich it passed to th einclined conveyer and delivered by the latter conveyor a distance beyondthe side of the track. As the inclined and vertical conveyers are madeto revolve at a much greater speed than the horiztmtal conveyors, theyare enabled to carry ol't' all the snow delivtn'ed by the latter withoutinconvenience or choking.

11: in practice it is found desirable,the gearing contained between thearms 1 1. and .12 may be inclosed by any suitable :l'orm of casing.

I desire it to be distinctly understood that I do not confine myself tothe mechanism illustrated for driving the snow-wheel and conveyors, asany other well-known or approved means maybe employed without departingfrom the spirit of the invention.

Having thus described my invention, 1 claim a s new and desire to secureby Letters llatent-- 1. In asnow-plow, the combination, with a pocketedwheel, of horizontal ctmveyers and an essentially vertical eonveyerlocated between the horizontal coi'iveyers, substantially as shown anddescribed.
